FP: Complex geometries at a reduced cost, what does that mean? The level of complexity of 3D printed core does not affect the cost. Very difficult components, such as water jacket cores or cores for hydraulic applications, can be produced cost-effectively. In the case of simple castings, however, it is worth considering whether it pays off for the foundry in question in terms of conventional production methods and the associated manual work, as well as the possible rejects.
FP:如何理解降低复杂几何形状产品的生产成本？ 3D打印砂芯的复杂程度不影响成本。非常复杂的芯子， 如水套芯或液压铸件用芯，可以获得很好的成本效益。然 而，对于形状简单的铸件，就传统的生产方法和相关的手 工作业以及可能的废品而言，是否对铸造厂有利值得考 虑。
FP: For prototypes, this technology is already being used worldwide. How far along is series production? Since the delivery of the first printer in 2001, we have been able to sell over 170 3D Core and Form printers in 21 countries, with the inital focus on prototype production. Over the last few years, we have been able to increase the productivity of our systems and more customers are now successfully using 3D printers in the production of small and medium-sized series. We are constantly working on the further development for mass production.
FP: 对于原型制造，这一技术已经在世界范围内使用。 距离批量生产应用还有多久？ 自2001年第一台打印设备交付以来，我们已在21个国家 销售超过170台3D打印设备，主要用于原型生产。在过去 的几年中，我们已经尽可能提高系统的生产效率，现在越 来越多的客户正在成功地使用3D打印设备生产中、小批量 的产品。我们不断为进一步开展大批量生产而努力。
FP: Let’s talk numbers. As far as productivity is concerned, what is the performance data of your machines? With pleasure. We differentiate between two machine types for ExOne - S-Print and S-Max. The S-Print is used by foundries primarily for the production of prototypes, while the S-Max is also used in the series. The difference lies in the available space. While the S-Print has a capacity of 160 liters (installation space 800 x 500 x 400 mm), the S-Max offers 1260 liters (installation space 1800 x 1000 x 700 mm). But it is not just the volume of space that differentiates the systems from one another; of course, productivity is crucially important. While the S-Print realizes a printing capacity of approx. 20 liters per hour, we can offer with the S-Max a machine which can produce 100 and more liters per hour. I would like to clarify this with reference to the cycle times: In a 4 cylinder water jacket core, printed on a serial machine in inorganic, we produce 24 cores in 90 minutes. In Furan, up to 168 cores can be produced in under 9 hours. The printing time in 3D printing always depends on the process and layer height. Currently, layer times to print a shift in 15 seconds are possible.
FP:我们来讨论一下数据吧。就生产力而言，设备的性能 数据是什么？ 很愿意为您介绍，ExOne有两种设备类型： S-Print和 S-Max。S-Print主要用于铸造厂的原型生产，而S-Max可 以用于批量产品生产。不同之处在于可用的空间，S-Print 的容量为160升(安装空间800 x 500 x 400 mm)，S-Max 的容量为1260升(安装空间1800 x 1000 x 700 mm)。 不过，不仅仅是空间的体积将系统彼此区分；生产效率 至关重要。S-Print打印能力约20升/小时，S-Maxm目前 可以实现打印能力为100升/小时或更多一些。
我想就生产周期进行说 明： 例如用批量生产的无机粘 结剂打印设备生产4缸的水套 芯，可以在90分钟内生产24 个芯子。用呋喃树脂，可在9 小时内生产168个芯子。3D 打印设备的打印时间始终取决 于打印过程和层高。目前， 在15秒内打印1层是可以实现 的。
